Next-Gen Concrete Protection

SlopeShield Diagram WebImage 01SlopeShield Plus SA gives contractors the flexibility they need with today's demanding schedules and labor-challenged market.

Benefits:

  • Apply as early as day-6 after a concrete pour or directly to damp concrete during reroofing
  • Prevents weather-related rewetting enabling early dry-in
  • Allows interior trades to safely begin BEFORE completing cure cycle
  • Eliminates curing calendar resets avoiding costly setbacks
  • Streamlines sequencing, protects the structure, keeps project moving
  • Saves time, labor, and expensive project setbacks

Green, Fresh Pour Structural Concrete

Install SlopeShield Plus SA over green concrete a minimum of 5 days after pour. Ensure the surface is dry to the touch and meets all the required preparation requirements published in the installation instructions.

Lightweight Insulating Concrete

SlopeShield Plus SA can be applied to  lightweight insulating concrete. Substrate preparation includes priming the surface with sodium silicate approximately two days after the pour to lock in free lime and stabilize the surface chemistry.

Applying SlopeShield Plus SA on day-6 of the cure process:

  • Allows interior trades to begin work safely and sooner
  • Eliminates curing calendar resets to avoid costly project delays
  • Prevents weather-related rewetting and enables early dry-in
Upon full cure, following American Concrete Institute (ACI) guidelines, SlopeShield Plus SA creates a walkable surface with excellent traction and supports construction equipment

 

Reroof: Over High Moisture Content Concrete

SlopeShield Plus SA can be applied over existing concrete with high moisture content if the surface is dry to the touch. Applying SlopeShield Plus SA eliminates rewetting—even after rain—reducing schedule uncertainty and maintaining interior operations.

Cure Times and Installation Guidance

SlopeShield Plus SA does not accelerate the natural curing process of concrete; proper curing is still essential for substrate integrity and performance. While SlopeShield Plus SA protects the concrete from external moisture and allows internal vapor to escape, VaproShield recommends following American Concrete Institute (ACI) guidelines for cure time. This guideline aligns with industry standards to ensure optimal results.

Roof-to-Below-Grade Protection

Large-format industrial buildings such as data centers require continuous, high-performance building enclosure systems to safeguard the critical infrastructure within. Moisture intrusion, uncontrolled air leakage, and enclosure failures can compromise uptime, disrupt operations, and increase long-term risk. A fully integrated roof-to-below-grade enclosure solution from VaproShield delivers continuous protection, helping preserve mission-critical assets while enhancing energy efficiency and long-term facility value.

Proven Solutions

Roof to Below Grade Air Barrier Solutions

VaproShield’s integrated air barrier systems deliver continuous, airtight protection from roof to below grade, strengthened by a strategic alliance with Polyguard—providing one system, one warranty, and complete confidence.

Walmart Headquarters

Bentonville, Arkansas
Over 1,000,000 sq.ft. of VaproShield’s self-adhered roof and wall air barrier membranes were installed across Walmart’s 12-building mass timber office campus over 24 months. SlopeShield Plus SA, installed on the roof decks, delivered mass timber protection for construction crews and machinery—all while simultaneously drying the mass timber through moisture vapor diffusion.

Amazon DII5 Delivery Station

Elkhart, Indiana
The large-scale 171,000 sq.ft. high-tech delivery station opted for the trusted mass timber protection solution from VaproShield. PanelShield SA, applied in the factory to large format panels, doubled as robust protection during transport and construction and mitigated moisture damage during installation and throughout the life of the building.

Hi-Tech Campus

Redmond, Washington
Built in the rainy Pacific Northwest, over 50,000 sq.ft. of SlopeShield Plus SA roofing membrane protects the mass timber decking on one of the newest buildings on the Microsoft campus. Durable under heavy traffic and resistant to ponding water, it provided slip-resistant traction for crews while allowing the structure to dry and breathe, delivering permanent, vapor permeable moisture protection.
